Status of case:Officers involved in the shooting have been cleared by the Wilmington Police Department and Wilmington’s City Solicitor. As of Thursday, the Delaware Attorney General continues to investigate the shooting.

Bruce Alfonso Altenburger was from Landenberg, Pennsylvania, according to his obituary, and he had worked for the DuPont Co.'s safety-health-environmental department.

A graduate of SUNY Buffolo, the obituary said, Altenburger also was an avid racquetball player, sailor and beach goer.

On Jan. 23, police were called to the 1700 block of W. 13th St. for a report of a "distraught" and potentially armed man.

Arriving officers encountered Altenburger, who was armed with a handgun and fatally shot him, police said.

Altenburger left behind a wife and two sons, his obituary said. Family could not be reached for comment.

The case was the first fatal shooting by Wilmington officers since Sept. 23, 2015, when 28-year-old Jeremy "Bam" McDole was shot to death by four city officers.
